Of the vehicles we've measured so far using this methodology, the Genesis Electrified GV70 is the quietest at a 70-mph cruise ...

For decades, carmakers treated cabin noise as a single number problem, something to be tamed with thicker glass and extra ...

Engineers are not just adding more insulation, they are reinventing how interior noise is captured, modeled, and judged so ...

Accurately measuring output noise and ripple requires a basic understanding of the high frequency nature of noise. Very often, “noise” (as commonly measured) is actually the vector sum of common- and ...

Why You Can’t Just Use a Spectrum Analyzer Industry has an increasing demand for spectrally pure signals in applications such as imaging radar, mobile communications, satellite communications, weather ...

Three tools are typically used to measure vibrational noise (noise) - a storage Oscilloscope (scope); a vibration sensor (sensor), which is generally a 'seismic grade' accelerometer 1; and a ...

What are the loudest sounds at UB? Where are the university’s quietest spots? What unlikely noises here are around 60 decibels, the level typically associated with a normal conversation between two ...

This video from Charlotte Pipe shows a sound test of various DWV plumbing systems. Materials tested are cast iron soil pipe, solid wall PVC and foam core PVC, with and without insulation products.

Nuclear physicists proposed a method to measure the speed of sound characterizing matter created in nuclear collisions. Heavy nuclei consist of hundreds of protons and neutrons (belonging to a group ...

Martian landers have been able capture measurements of wind speeds -- some gauging the cooling rate of heated materials when winds blow over them, others using cameras to image 'tell-tales' that blow ...
